[sudo-discuss] LED nube

[Jake]

i don't understand the question.  There are solder points at both ends of each
discrete 3-LED circuit.  You can splice this tape back together after cutting
it if you solder carefully.

if you want to use multiple power supplies, they should be connected to
separate sections of LED tape, power supplies' outputs should not be paralleled
together.
